Commit d178e034 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature to dpi code") replaced usage of platform data version with SoC matching to configure DPI VDDS. The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it. The result was observed on OpenPandora with OMAP3530 where the panel only had the Blue channel and Red&Green were missing. It was not observed on GTA04 with DM3730.

I believe the intention of the commit 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match. Fixes: 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") Cc: stable@vger.kernel.org # 4.14 Signed-off-by:

Support the "cec" optional clock. The documentation already mentions "cec" optional clock and it is used by several boards, but currently the driver doesn't enable it, thus preventing cec from working on those boards. And even worse: a /dev/cecX device will appear for those boards, but it won't be functioning without configuring this clock. Changes: v4: - Change commit message to stress the importance of this patch v3: - Drop useless braces v2: - Separate ENOENT errors from others - Propagate other errors (especially -EPROBE_DEFER) Signed-off-by:

If the device tree for a board did not specify a cec clock, then adv7511_cec_init would return an error, which would cause adv7511_probe() to fail and thus there is no HDMI output. There is no need to have adv7511_probe() fail if the CEC initialization fails, so just change adv7511_cec_init() to a void function. In addition, adv7511_cec_init() should just return silently if the cec clock isn't found and show a message for any other errors. An otherwise correct cleanup patch from Dan Carpenter turned this broken failure handling into a kernel Oops, so bisection points to commit 7af35b0a ("drm/kirin: Checking for IS_ERR() instead of NULL") rather than 3b1b9750 ("drm: adv7511/33: add HDMI CEC support").

drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.

This just changes the file to report them as zero, although maybe even that could be removed. I checked, and at least procps doesn't actually seem to parse the 'stack' file at all. And since the file doesn't necessarily even exist (it requires CONFIG_STACKTRACE), possibly other tools don't really use it either. That said, in case somebody parses it with tools, just having that zero there should keep such tools happy. Signed-off-by:

This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags. The script to do this was: # places to look in; re security/*: it generally should *not* be # touched (that stuff parses mount(2) arguments directly), but # there are two places where we really deal with superblock flags.

Currently we make page table entries dirty all the time regardless of access type and don't even consider if the mapping is write-protected. The reasoning is that we don't really need dirty tracking on THP and making the entry dirty upfront may save some time on first write to the page. Unfortunately, such approach may result in false-positive can_follow_write_pmd() for huge zero page or read-only shmem file. Let's only make page dirty only if we about to write to the page anyway (as we do for small pages). I've restructured the code to make entry dirty inside maybe_p[mu]d_mkwrite(). It also takes into account if the vma is write-protected. Signed-off-by:
